What does error code p051 on a 2003 jeep grand Cherokee overland mean?
It's an oxygen sensor malfunction. Believe it's bank 2 (right side), upstream. May need clarification on exactly which one of the four.
Why don't we run out of the important gases that we need to saty alive?
Like oxygen, we need oxygen to our life because we are able to breath and we need carbon dioxide for plants
Why do you need to have a sparger in fermentor?
A sparger, essentially a perforated cover places below the agitator, allows one to control the size of oxygen bubbles produced during fermenation. This must be under close controls as large bubbles do not afford for maximal surface-area to volume and are not easily absorbed by the target organism. At the same time, it forbids bubbles becoming too small either, which would produce foam that interfered with downstream processing.
I have a Code 41 for your 1995 Nissan Pickup what do you need to do?
Code 41 is an "air temperature sensor" fault. (KA24E Engines only). Check the circuit for "open circuit" or "shorted circuit" first. Change sensor.

Do you need upstream or downstream oxygen sensor for a 2000 Mitsubishi Galant?
It should be equipped with both.
Is there a difference between the upstream and the downstream oxygen sensor as far as the part number?
It depends on the make and model of your car. Sometimes the wires of the downstream sensor need to be longer than the upstream sensor. This would mandate a different part number. Sometimes the upstream sensor is a "wideband" or "universal" type O2 sensor, as opposed to a "switching" type O2 sensor (which is always found in the downstream position). This would also mandate a different part number.
How many oxygen sensors are on a 2000 grand prix se 3800?
There are 2 oxygen sensors. 1 sensor located right behind the engine (which is known as the upstream sensor) and one behind the catalytic converter (known as the downstream sensor). It is located at about the middle point of the vehicle on the top of the pipe. You will need an O2 sensor socket to remove the upstream sensor, and you will need an O2 sensor wrench with a pivoting handle to remove the downstrean sensor.
Where is the upstream oxygen sensor located on a 1999 Ford Taurus SE with a 3.0L V6 engine and how do you go about changing one if only the upstream is bad do i need to change the downstream as well?
The upstream 02 sensor is usually located shortly after the exhaust manifold, before the converter. That is the one that controls how the car runs. The downstream sensor, after the converter tells the computer if the converter is doing it's job or not. It does not affect performance, but you might have to live with a check engine light being on. There are probably 2 of each on a V6.
Where is the bank 2 sensor located on a 2005 Chrysler 300 2.7?
There is an upstream and downstream O2 sensor (bank1 and bank2). Upstream is located close to the engine bay in FRONT of the cat converter, and 2 is located behind the converter.
How many O2 sensors does a 2001 Kia Optima have?
two. one air/fuel ratio sensor or upstream sensor, and one oxygen sensor or downstream sensor. when replacing them make sure they are the cause and not the symptom of something else and also only use direct fit, universal are known to have to many problems and need to be wired in
Where are the oxygen sensors and how do you replace them on a 1998 ford explorer?
We need to know if your code relates to upstream or downstream errors. If it says downstream you are having a problem with the converters. If it states upstream there can be many reasons for the code. Is it running good. Bad. Smoking at all. Let me know and we can go from there
Where is the o2 sensor in a 94 ford ranger?
O2 sensors are always threaded right into the exhaust pipe. Follow the pipe until you see the sensor. If this model has more than one, you may need to know which bank your looking for (V6 only) and whether its the upstream or downstream sensor. Bank 1 is whichever side of the engine cylinder 1 is on. Upstream is before the catylitic converter and downstream is after it.
Where is located oxygen sensor 1998 Mercury Villager?
When you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side; Bank 2 is on the driver's side. Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat). Normally it is the upstream sensors (sensor 1) that go first. They see the harshest conditions. You will need; Oxygen Sensor Socket Anti-Seized Penetrating Oil Sometimes it will take 15 minutes or take a few hours it depends on your luck…
Where is the O2 Sensor on 1995 Ford Taurus?
Oxygen SensorWhen you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side - or closest to the firewall; Bank 2 is on the driver's side - the front bank.Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat).Normally it is the upstream sensors (sensor 1) that go first.

Code P0155 2001 gmc 2500 hd?
Upstream Oxygen Sensor heater performance. That will be the first oxygen sensor in the exhaust pipe ( closest to the engine ) on the passenger side head. You need to check the wireing connector that hooks to the oxygen sensor for a broken wire are bad connection. If you find no problems, then replace oxygen sensor.
Where is the oxygen sensor bank 1 sensor 1 on a Chevrolet 2004 Impala?
Oxygen SensorSome vehicles have (2) and some have (4) O2 sensors.When you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side; Bank 2 is on the driver's side.
